This is still bad. We should modify convertDefault.sh to work as a filter, namely 'convertDefault.sh file.eps' should write its output to stdout and not to the disk. In LyX, the necessary modification is to create a pipe when calling to convertDefault.sh. This will be much faster than the current method.
